Trigger Finger / Trigger Thumb
বাংলা নাম: আঙুল আটকে যাওয়া / ক্লিক করা আঙুল
Medical term: Stenosing flexor tenosynovitis
এটি শিক্ষামূলক ক্লিনিক্যাল নোট। Steroid injection, NSAID, PPI, dose adjustment—রোগীর বয়স, DM, CKD, pregnancy, ulcer history, anticoagulant use অনুযায়ী চিকিৎসকের সিদ্ধান্তে হবে।
1) Definition — সংজ্ঞা
Trigger finger হলো এমন একটি hand condition যেখানে flexor tendon ও tendon sheath/A1 pulley-এর জায়গা সংকুচিত বা thickened হয়ে যায়। ফলে আঙুল বাঁকানো/সোজা করার সময় tendon সহজে glide করতে পারে না—আঙুল click, catch, lock করে এবং কখনও bent position-এ আটকে যায়। AAOS ও ASSH একইভাবে A1 pulley thickening/tendon gliding problem-কে মূল pathology হিসেবে বর্ণনা করেছে।
2) Cause / Etiology & Pathophysiology — কারণগুলো
মূল Pathophysiology
- A1 pulley thickening / stenosis:
আঙুলের গোড়ার palm-side-এ A1 pulley নামের tunnel থাকে। এটি thick/ inflamed হলে tendon আটকে যায়। - Flexor tendon nodule:
tendon-এর ওপর ছোট nodule/গুটি তৈরি হতে পারে; এই nodule pulley-এর নিচ দিয়ে যাওয়ার সময় আটকে গিয়ে clicking/locking করে। - Tendon sheath inflammation:
repetitive friction → inflammation → swelling → tunnel আরও narrow → triggering বাড়ে।
Risk factors / Causes
- Repeated gripping / squeezing / hand overuse
যেমন: prolonged writing, mobile gripping, tools use, heavy lifting, kitchen/industrial work। - Diabetes mellitus
Diabetic রোগীর trigger finger বেশি দেখা যায় এবং injection response তুলনামূলক কম হতে পারে। StatPearls diabetes, thyroid disease, RA, gout, amyloidosis, carpal tunnel syndrome—এসব association উল্লেখ করেছে। - Rheumatoid arthritis / osteoarthritis
- Hypothyroidism
- Gout
- Carpal tunnel syndrome
- Female sex, age >40–50 years
Mayo Clinic অনুযায়ী women over 50, diabetes, low thyroid function, RA—risk বাড়ায়। - Previous palm/finger trauma
- Post-operative hand swelling / prolonged immobilization
3) Symptoms — লক্ষণগুলো
Common symptoms
- আঙুল বাঁকানো বা সোজা করার সময় click/popping sound
- Finger catching / আটকে যাওয়া
রোগী বলে: “আঙুল হঠাৎ আটকে যায়, তারপর টান দিলে খুলে যায়।” - Morning stiffness
সকালে ঘুম থেকে ওঠার পর বেশি stiff; ব্যবহার করলে কিছুটা কমতে পারে। - Pain at base of finger/thumb
সাধারণত palm side-এ MCP joint/A1 pulley area-তে ব্যথা। - Tender nodule / গুটি অনুভব হওয়া
আঙুলের গোড়ায় চাপ দিলে painful lump পাওয়া যেতে পারে। AAOS trigger finger-এর লক্ষণ হিসেবে tender lump, catching/popping/locking এবং finger stuck in bent position উল্লেখ করেছে। - Locking in flexion
severe হলে finger bent position-এ আটকে যায়; অন্য হাতে সোজা করতে হয়। - Reduced grip strength
pen ধরা, cup ধরা, দরজার handle ধরা, নামাজ/কাজের সময় সমস্যা। - Pain may radiate
palm থেকে finger বা forearm side-এ discomfort যেতে পারে।
Severity grading — সহজভাবে
| Grade | Clinical picture |
| Grade I | Pain/tenderness, no obvious locking |
| Grade II | Active movement-এ catching/clicking, কিন্তু নিজে খুলে যায় |
| Grade III | Lock হয়; অন্য হাতে straighten করতে হয় |
| Grade IV | Fixed flexion contracture / স্থায়ীভাবে বাঁকা |
4) Clinical Diagnosis — কীভাবে clinically diagnosis করবেন
Trigger finger সাধারণত clinical diagnosis। History + physical exam যথেষ্ট। Imaging routine লাগে না। StatPearls ও primary-care review-এ diagnosis mainly clinical বলা হয়েছে।
History
- কোন finger/thumb affected?
- morning stiffness আছে কি?
- clicking/catching/locking আছে কি?
- repetitive hand work আছে কি?
- DM, RA, thyroid disease, gout আছে কি?
- previous trauma/surgery আছে কি?
- pain duration: acute/subacute/chronic?
Examination
- Inspection: swelling, deformity, fixed flexion আছে কি?
- Palpation: A1 pulley area-তে tenderness/nodule।
- Active flexion-extension test: রোগীকে finger bend/straight করতে বলুন—clicking/locking দেখা যায়।
- Passive movement: joint stiffness vs tendon catching আলাদা করুন।
- Neurovascular exam: sensation, capillary refill।
- Look for associated conditions: Dupuytren’s contracture, carpal tunnel sign, RA deformity।
5) Investigations — কোন test লাগবে?
Usually not required
- X-ray: routine trigger finger diagnosis-এর জন্য দরকার নেই।
When specific investigation করবেন
- Ultrasound of finger/palm:
uncertain case, occult nodule, A1 pulley thickening, tenosynovitis, guided injection দরকার হলে useful। 2024 BMC review ultrasound and rehabilitation-based assessment নিয়ে trigger finger diagnosis/management আলোচনা করেছে। - X-ray hand:
যদি trauma, osteoarthritis, fracture, joint pathology সন্দেহ হয়। - Blood tests — selected patients only:
- Fasting glucose / HbA1c — diabetes screening/control
- TSH — hypothyroid suspicion
- ESR/CRP, RF/anti-CCP — RA suspicion
- Serum uric acid — gout suspicion
- MRI:
routine নয়; mass/tumor, atypical pain, failed treatment with unclear diagnosis হলে rare use।
6) Differential Diagnosis — কী কী রোগ থেকে আলাদা করবেন
- Dupuytren’s contracture
- Flexor tendon injury
- Osteoarthritis of MCP/PIP/DIP joint
- Rheumatoid arthritis tenosynovitis
- De Quervain tenosynovitis — thumb/wrist radial side pain
- Carpal tunnel syndrome
- Gouty tenosynovitis
- Ganglion cyst / tendon sheath cyst
- Infective flexor tenosynovitis — red flag: severe pain, swelling, fever, Kanavel signs
7) Complications of Disease — রোগের জটিলতা
- Persistent locking:
আঙুল বারবার আটকে গেলে daily work severely impaired হয়। - PIP joint stiffness:
দীর্ঘদিন bent position-এ থাকলে joint stiff হয়ে যায়। - Fixed flexion contracture:
severe chronic case-এ আঙুল স্থায়ীভাবে বাঁকা হয়ে থাকতে পারে। - Reduced hand function:
grip weakness, writing difficulty, household/professional কাজ কমে যায়। - Pain-related disuse:
ব্যথার কারণে রোগী finger নাড়াচাড়া কমালে stiffness আরও বাড়ে। - Recurrence:
conservative treatment বা injection-এর পর কিছু রোগীতে আবার symptoms ফিরে আসতে পারে।
8) Treatment Management — Stepwise
AAFP/StatPearls অনুযায়ী treatment options হলো activity modification, splinting, NSAID/analgesia, corticosteroid tendon-sheath injection, এবং failed/severe case-এ surgery। AAFP 2023 intrasheath corticosteroid injection trigger finger-এ effective হতে পারে বলেছে; StatPearls steroid injection-কে cost-effective, less invasive initial treatment হিসেবে বর্ণনা করেছে।
Non-pharmacological
- Activity modification: repeated gripping, forceful squeezing, vibrating tools avoid।
- Night splint: MCP/finger extension splint, সাধারণত 4–6 weeks।
- Warm water soak: সকাল stiffness কমাতে 10–15 min।
- Tendon gliding exercise: pain-free range-এ।
- Diabetes/RA/thyroid/gout control।

- Heavy lifting করলে gloves + wider grip ব্যবহার
- Diabetes control: HbA1c target individualized
- RA/hypothyroid/gout properly treat করা
- Morning stiffness থাকলে warm water soak + gentle tendon gliding
- Early clicking হলে ignore না করে splint/activity modification শুরু করা
- Painful locked finger জোর করে টেনে সোজা না করা
Overview / Summary
Trigger finger হলো A1 pulley stenosis + flexor tendon gliding problem। প্রধান লক্ষণ হলো palm-side pain, clicking, catching, locking, morning stiffness। Diagnosis সাধারণত clinical। Mild case-এ splint/activity modification/analgesic; persistent locking-এ corticosteroid tendon-sheath injection; severe বা failed case-এ A1 pulley release surgery definitive।
Actionable Plan / Steps
- Grade করুন: pain only, clicking, locking, fixed deformity—কোন stage?
- Risk factor check করুন: DM, RA, hypothyroid, gout, repetitive hand work।
- Mild case: activity modification + night splint 4–6 weeks + paracetamol/NSAID short course।
- Moderate locking: steroid tendon-sheath injection by trained doctor; diabetic হলে glucose monitor।
- Failed/recurrent/severe locked finger: orthopedic/hand surgeon referral for A1 pulley release।
- Red flag: severe swelling, redness, fever, whole finger tenderness, passive extension pain → infective flexor tenosynovitis exclude urgently।
